Optical properties of dibenzo[d,d′]thieno[3,2-b;4,5-b′] dithiophene monocrystals: The effect of intermolecular interactions

The polarized UV-visible absorption spectra of dibenzo[d,d′]thieno[3, 2-b;4,5-b′]dithiophene single crystals are reported and interpreted to definitively attribute the observed bands and their polarizations. The results provide information on the intermolecular interactions and on the aggregation in the condensed phase, which can be of either herringbone- or H-type, depending on the electronic transition taken into considerations, with consequences on the order and polarization of the absorption bands. A relatively easy method is also discussed to obtain information on the structural/morphological properties of different types of samples, including thin films, which have been recently proposed for high-performance organic film-effect transistors for their high ionization potential and photostability.

Electrochemical Synthesis of Thienoacene Derivatives: Transition-Metal-Free Dehydrogenative C?S Coupling Promoted by a Halogen Mediator

The first electrochemical dehydrogenative C?S bond formation leading to thienoacene derivatives is described. Several thienoacene derivatives were synthesized by dehydrogenative C?H/S?H coupling. The addition of nBu4NBr, which catalytically promoted the reaction as a halogen mediator, was essential.

Linear and Angular Heteroacenes from Double-Electrophilic Cyclization (DEC) and DEC-Reductive Elimination of Diynes

Linear and angular heteroacenes are prepared from terminal alkynes bearing tethered nucleophiles in two steps. Linear heteroacenes are formed from the homocoupling of these alkynes followed by reaction with a double electrophile (ECl2) to induce a tricyclization reaction cascade involving double-electrophilic cyclization (DEC). Related angular heteroacenes are formed from the prior substitution of the chloro groups in ECl2 with the same terminal alkyne followed by reaction with AuCl3 to produce a DEC-reductive-elimination (DECRE) reaction.
